Sensor Matsin Taya Waje (Mai watsawa)

Bayani

Ana shigar da firikwensin matsa lamba na waje a cikin tashar mota kuma ta atomatik yana saka idanu akan matsa lamba na taya, zazzabi, da matakin baturi.An shigar da firikwensin ciki da na'urar firikwensin waje a wurare daban-daban, amma saboda an shigar da firikwensin waje kai tsaye a bakin gas. daidaiton ma'aunin ma'aunin taya ba zai yi tasiri ba. A cikin auna zafin taya, firikwensin waje zai sami kuskuren digiri 1-2 idan aka kwatanta da wanda aka gina a ciki.

Na'urar firikwensin matsin lamba na waje yana amfani da na'ura mai ba da hanya tsakanin hanyoyin sadarwa don aika bayanan matsa lamba daga waje na taya zuwa tsarin mai karɓa na tsakiya, sannan yana nuna bayanan matsa lamba na kowace taya. Lokacin da matsa lamba na taya ya yi ƙasa sosai ko iska ta zubar, tsarin zai ƙararrawa ta atomatik.Tsarin watsawa ya ƙunshi sassa masu zuwa: ɓangaren lantarki (ciki har da ma'aunin taya, crystal oscillator, eriya, RF module, ƙananan mita, baturi) da kuma ɓangaren tsarin (harsashi, madauri).

Moduluwar matsa lamba ta taya: A cikin tsarin watsawa, ma'aunin matsa lamban taya wani nau'i ne mai haɗaka sosai wanda ya gaji MCU, firikwensin matsa lamba, da firikwensin zafin jiki. Ta hanyar shigar da firmware a cikin MCU, matsa lamba, zafin jiki, da bayanan hanzari za'a iya tattarawa da sarrafa su yadda ya kamata, kuma a aika ta tsarin RF.

Crystal oscillator: Oscillator crystal yana ba da agogo na waje don MCU, kuma ta hanyar daidaita rajistar MCU, ana iya tantance sigogi kamar mitar tsakiya da ƙimar baud na siginar RF da mai watsawa ya aiko.

Eriya: Eriya na iya aika bayanan da MCU ke watsawa.

Modulin mitar rediyo: An ɗauko bayanai daga ma'aunin matsi na taya kuma an aika ta mitar rediyo 433.92MHZFSK.

Ƙananan eriya: Ƙananan eriya na iya amsawa zuwa ƙananan sigina kuma aika su zuwa MCU.

Baturi: Yana iko da MCU. Ƙarfin baturi yana da babban tasiri akan rayuwar sabis na mai watsawa.

PCB: Kafaffen abubuwan da aka gyara da kuma samar da amintattun hanyoyin haɗin lantarki.

Shell: Yana keɓance kayan lantarki na ciki daga ruwa, ƙura, wutar lantarki, da sauransu, yayin da kuma yana hana tasirin injin kai tsaye akan abubuwan ciki.
